whom it may concern Be it known that I, ADAM H. PRENZEL, a ieitize'n of the United States, residing at ,Halifaxfln the county of Dauphin and State {of Pennsylvania, have invented certain Imro'vements in Machines for Use in Lasting oots and Shoes, of which the following de- ,sfcription in connection with the accompanying drawings, is a specification, like reference characters on the drawings indi- ..eati like parts in the several figures.

Jhrs invention relates to machines which are especially adapted for use in connection with the lasting of boots and shoes and is herein shown and described in an embodi- .ment designed particularly for use in lasting stitch-down shoes. Up to the present time substantially all machines intended for use in the lasting of stitch-down shoes have been designed to shape at one operation either the whole upper or the heel or the toe pertion of the upper. Progressive lasting, in which the upper has been brought into and secured in its final lasted condition in a stepwise manner, has been almost. unused. It will be apparent that in the lasting of stitchdewn shoes there .are numerous disadvaniages which result from the employment of machines with which it is attempted to last either the whole or a substantial part of the shoe upper at a single operation. In the first place, if the means for conforming the upper-to the shape of the last is eflicient for this purpose, it must necessarily, in the case of, the lasting of stitch-down shoes, interfer-e with properly securing the upper in lasted condition. The most common practice with machines of this type has been to secure the upper in lasted condition by cementing the outturned flange down upon the outsole. It will be obvious, however, that even with the best cement this mode of securing the upper in lasted'condition must necessarily be unsatisfactory and must be totally impracticable when the upper has been stretched considerably to conform it to the last. Although the machines with which it has been attempted to last either the whole or a substantial part of the upper at a single operation have been unsatisfactory, the roblem of the progresslve lasting of stitehown shoes has presented so many zd-iififiulties that very few attempts have been made to solve it. One of the most obvious difficulties has been to draw the upper down over the side of the last in order to conform'the upper to the last and then, without releasing the upper, to secure it firmly in lasted position and at the same time leave the lower marginal portion of the upper outturned upon the projecting margin of the sole to form the outturned flan e to which the sole is to be secured. It will be apparent that any fastening which is to hold the upper securely in its lasted positlon must exert at least a considerable part of its holding power close to the edge of the last. Not only have the lasting machines which have been in commercial use for lastin shoes been totally unadapted for the lasting of stitch-down shoes, but the fastenings employed in such machines have been unsuited for properly securing the stitchdown upper in its lasted condition.

An object of the present invention is to provide a machine for usein the lasting of boots and shoes which will be especlally adapted to effect the progressive lastin of stitch-down shoes and b the use of w ich the upper may be con ormed to the last more closely than has heretofore been customary in the manufacture of this type of shoes.

Another object of the invention is to provide a machine that will not only bring about a proper conformation of the upper to the last but will insert a fastenin of a type peculiarly suited for securing t e upper in lasted position and which may furthermore remain as a permanent fastening to reinforce the attachment of the sole to the upper.

Important features of the invention are the novel relative moyement of the last and the upper engaging means whereby the upper is drawn down over the rounded sides of the last and conformed closely to the last, the provision of means for eflecting an initial lasting movement of the shoe engaging parts before the fastening inserting mechanism is actuated wherebv the probable last ing effect may be observed before the upper is secured in lasted position, the provision of novel means for gripping the upper when it is desired to secure more than the usual drawing or stretching action upon the upper, and the novel means fior presenting the work for the fastening inserting operation whereby the fastening is so located as to be most effective as a securing means for all purposes.

Other features and objects of the inventionwill appear from the following descrip tion and claims when considered in connection with the accompanying drawings.

In the accompanying drawings,Figure 1 is a side elevation of a machine embodying the invention, the base being broken away to permit showing the machine on a larger scale; Fig. 2 is a detail perspective of the parts to which the present invention particularly relates, these parts being shown in operative osition; Fig. 3 is a detail side elevation siowing the manner of using the machine when the work does not require much stretching; Fig. 4 is a perspective view of a preferred form of nozzle.

The mechanism for makin and driving the staples may be of any well-known type, that herein shown being substantially the same as that described in United States Letters Patent to V. H. Borden, No. 1,016,930, granted Feb. 13, 1912. This mechanism is mounted in a head 2 carried upon a standard 4 and comprises a staple driver 6 attached to a driver bar 8 which is spring-operated, the driver operating spring acting upon an arm 10 fulcrumed at 12 upon a. bracket 14 carried by the head 2. The staple forming mechanism and the wire feeding mechanism are identical with those described in the Letters Patent above referred to except that the parts are fitted to operate upon much finer wire than is usually used in this type of machine.

The driver 6operates in a staple guiding throat which extends into a nose or nozzle 16 which is of a peculiar shape and which constitutes one of the characteristic features of the present invention. As shown in each of the fi ures, this nozzle is tapered to a comparatively thin end, that is, the edge which is to engage the upper of the shoe to be lasted is comparatively thin from front to back. The dimension which extends along the shoe or along the edge. of the last is preferably sufiicient to ive a good bearing surface and is also pre ferably sufiicient to carry a throat for a staple of substantial width. Further reference to characteristic features of the nozzle 16 will be made here inafter.

When the machine is to be used with a last having sharply curved portions along its lower edge it is advantageous to concave the nozzle 16 transversely upon the side adjacent to the last as shown in Fig. 4. Furthermore, as shown in th drawings, a longitudinal concavity upon this side serves to accommodate the curvature of the transverse contour of the last.

In one aspect the lasting operation consists in causing the nozzle 16 to force the upper into the angle between the last and the projecting margin 'of the sole of a stitchdown shoe or into the angle between the shoulder of a shouldered stitch-down sole and the projecting margin of said sole, these two operations being considered to be equivalents. In order to effect the relative movement of the nozzle and last or the nozzle and the sole against which the upper is to be pressed, means is provided for supporting the sole, and in the construction shown this means has a movement toward and away from the nozzle 16. The sole support herein shown comprises an anvil 18 which has in its normal positions an inclined surface 20 which is offset at :22 to provide a shoulder in the line of the movement of the anvil toward and away from the nozzle 16, this shoulder serving to support the sole against the work-clamping pressure and also against the thrust of the staple driving operation. To provide for varving the inclination of the sur ace 20 the anvil 18 is pivoted at 24 upon a head 26 carried by a rod or post 28 arranged to slide vertically in a born 30. Thehorn30 is itself carried by a horn post 31 arranged to slide in a vertical bore -in'a bracket 32 which has a stem 34 clamped in a Zecpnd bracket 36 integral with the standar The anvil 18 is normally held in its different positions of angular adjustment by means comprising an armintegral with the anvil 18 to which is pivotally connected a rod 40 threaded at its lower end and ar ranged 'to slide freely through'an opening in an arm 42 rigidly connected to two studs 44 and 46 which extend from the post 28 through a slot 48 in the horn 30, these studs serving to prevent the post 28 from turning in the bore in the horn 30. A stop nut 50 and a set nut 52 are threaded upon the rod 40, the stop nut 50 being held normally in engagement with the upper face of the arm 42 by a spring 54 which surrounds the rod 40 below said arm and bears against a second stop nut 56. An adjusting nut 58 serves to lock the stop nut in its different positions of adjustment. The adjusting nut 58 serves also as a stop which cooperates with an adjustable stop constituted by a screw 60 threaded throu h an arm 62 attached to the horn 30. T e screw 60 is providedwith a knurled head 64 by which it maybe turned, and is locked in its different positions of ad justment by a set nut 66.

The anvil 18 is preferably arranged so that it may be moved into operative relation to the nozzle 16 both by hand and by power. The provision for moving the anvil into operative relation to the nozzle 16 by hand is for the purpose of determining approxi mately the point at which the staple shall be inserted to secure the upper in lasted position and to determine whether or not the of the rod and for movement of the horn 30 relatively to the lever 68, when the lever is stationary, by forming a slot 7 8 in one side of said horn of suificent dimensions to ermit the desired relative movements. he

movement of the lever 68 to efiect the movement of the rod 28 can be effected either by hand through a handle 80 or by connections to a treadle 82, the said connections comprising a chain 84 hooked at one end to said treadle and at its other end to the outer arm of the lever 68. y

The illustrated power operated means for bringing the anvil 20 and nozzle 16 into cooperative relation to each other and for holding the parts in work clamping relation while thestaple is being driven comprises a lever 86 fulcrumed at 88 in the bracket 32, this lever having a rounded front end 90 which is confined in a slotin the horn post 31. The other end of the lever 86 is pivotally connected with the lower end of a. rod 92 which is connected at its upper end to the outer end of'a lever 94 fulcrumed. at 96 upon the head 2. Between its ends the lever 94 is provided with a cam roll which enters a cam groove in the side of a cam disk 98. The rod 92 is arranged to slide in the rear end of the lever 86 to provide lost motion for transmitting yielding pressure to the Work through the horn 30. The means for transmitting yielding pressure comprises a spring 100 confined between the collar 102 clamped upon the rod 92 and a washer 104 bearing against the upper side of the lever 86. a

From the foregoing description it will be noted that the anvil 20 may be first moved into cooperative relation to the nozzle 16 by hand and then clamped in operative position by a movement of the born 30 through the connections with the cam 98, or the anvil may be moved into operative position at the same time that the movement of the born 30 is effected. The preferable practice, however, is to secure the proper adjustment of the work between the nozzle 16 and the anvil 18 and the greater part of the wiping and stretching relative movement of these parts before the movement of the horn '30 is effected.

It will be noted that that face of the nozzle which performs the wiping action hereinafter described, that is, the face of the nozzle which is ad'acent to the last, is smooth, so that it wiil not in'ure the upper, an essential characteristic 0 'the construction of the nozzle being the location of this face close to that line of direction of the relative movement of the nozzle and the sole support. which passes through the delivery end of the staple guide in said nozzle. By this construction and arrangement of the lasting tool of this machine, for the first time in the art of making stitch-down shoes it is possible to stretch the upper of a stitchdown shoe over the last, wipe it down'the side of the last into the an lebetween the last andthe sole margin, an while the upper is thus held in lasted osition, insert a fastening in said angle so t at it will secure the upper tightly against the two sides of said angle exactly in its lasted position.

In the illustrated construction it will be seen that the wipin face of the nozzle lies well within an ang e of 25 to the line of direction of the relative movement of the nozzle and, the sole support, a deviation of less than 25, in other words a deviation at not more than a sharply acute angle, being essential both for securinga proper stretching and wipinghaction upon the upper, in order to draw t e upper tight over the last and to wipe it down the side of the last into the angle between the last and the sole margin, and also for locating the sta le or other fastening where it will ,secure t e upper firmly and exactly in lasted osition.

he best results are obtained when t e inclination of the wiping face vto the direction of the relative movement of the nozzle and the sole support approximates parallelism as closel as is consistent with proper strength in the wall of the nozzle, it belng also essential to proper lasting that the nozzle be so constructed that the delivery end of the staple guide in the nozzle will deliver the staple as close to the wiping face as is consistent with-strength in this wall of the nozzle.

From an inspection of Figs. 2 and 3 it will be noted that the shoe to be lasted, which has been assembled upon the last, is presented to the machine by first placing the sole of the shoe upon the inclined surface 20 of the anvil 18 with the parts in such position that when the anvil 18-.-is moved toward the nozzle 16 the nozzle 16 will enter the angle between the last and the projecting sole margin, first engaging the angle formed by turningout the lowermargin of-the upper and wiping the upper down over the side of the last and forcing 'the angle of the upper into the angle beto insure tucking of the upper under the overhanging edge of the rounded side of the last, as, for example, in the region of the shank, it is desirable that there be a tipping of the anvil, after the manual presentation of the work and after the anvil and the nozzle have been brought into cooperative relation to each other, so that the inclination of the surface 20 shall be somewhat steeper, thus permitting the nozzle to force the upper under the overhanging edge and permitting the staple to be driven so that its legs will project under the bottom edge of the last and be out of the way of the fastening used to secure the upper to the sole in the final attaching operation. This tipping movement of the anvil is provided for by the construction hereinabove described and the operation of this construction to secure this tipping movement is as follows: The stop nut 50 is so adjusted that the spring 54 will hold the anvil at the proper inclination when the parts are in the position shown in Fig. 1, or, at least, when the adjusting nut 58 has been moved out of engagement with the screw 60. The shoe being placed in po- -.sition upon the anvil 18 the operator either grasps the handle 80 or depresses the treadle 82 andmoves the anvil up until the nozzle 16 has engaged the angle of the upper and forced it substantially into the angle between the last and the projecting sole margin. During this movement there will be some tipping of the anvil due to the fact that the sole supporting surface of the anvil is in front of the pivot 24. This tip ing will obviously be against the pressure 0 the spring 5 4. When the machine is started to drive the staple the rod 92 Wlll be depressed and through its connections with the lever 86 will cause the horn 30 to be lifted until the lower end of the slot 48 engages the lower stud 46 upon the rod 28. If the stop 60 has been adjusted so that it engages the lower end of the adjusting nut 58 before the lower end of the slot 48 engages the stud 46 it will be obvious that the rod 40 will be pushed upwardly thus rocking the anvil 18 about its pivot 24 whereby the nozzle 16 Wlll be permitted to draw the upper around under the overhanging portion of the last and force it ti htly into the angle between the last and the sole margin. The inclination of the sole to the direction of the staple driving movement will also be varied this rocking of the anvil and the staple will thus be driven more nearly transverse to the direction of the pull of the stretched upper and also so that its legs project under the I last and out of the way of the latter fasten- I or small work, such as childrens shoes and sandals, it has been found that suflicient lasting and stretching can be effected by relative movement of-the sole support and the staple guiding nozzle. In lasting the lar er sizes of shoes it is sometimes found esirable to effect more stretching and drawing of the up er over the last than can be effected by the rictional engagement of the nozzle with the upper and the relative movement of the nozzle and the sole support into work clamping relation to each other. In order to obtain a better hold upon the upper when it is desired to efiect a greater stretching or pulling than can be efl'ected by the means hereinabove described, an upper gripping jaw 106 is provided, this aw being arranged to clamp the upper against the rear face of the nozzle 16. The j aw 106 is carried upon a slide 108 arranged to slide through guide openings in the head 2, this slide being held normally in its rearniost position by a spring 110 hearing at one end against one side of an opening 112 in the head 2 and at its other end against a collar 11.4 clamped upon the reduced portion of the slide 108. The jaw 106 is adjustably mounted in the slide 108, being pivoted at 116 and being held in different positions of angular adjustment about the pivot 116 by an adjusting screw 118 having at its upper end a rounded knob 120 which is confined in a bore 122 in the jaw 106, an opening into this bore through the side of the jaw 106 being provided by means of a slot 124. The screw 106 is threaded through a bracket 126 attached to the lower side of the slide 108 and is locked in its different positions of adj ustment by a set nut 128.

To eflect the movement of the jaw 106 into clamping relation to the nozzle 16 against the action of the spring 110, manually operated means is rovided comprising a bell-crank lever 130 ulcrumed at 132 between ears on a bracket extending from the head 2, one arm of the bell crank being provided with a slotted end 134 which receives a stud or screw 136 upon the side of the slide 108 and the other arm being arranged either to be operated by hand or to be 0 erated by connections to a treadle. In t e construction herein shown the other arm of the bell-crank lever 130 is connected by a chain 138 to the treadle 82 to which the lever 68 is connected. In this construction the parts arelso timed that the jaw 106 will move into clamping relation to the nozzle 16 before the anvil 18 is moved into operative relation to said nozzle. It will be noted that the jaw 106 recessed at 140 so that the anvil 18.Inay come up behind the jaw as it moves into cooperative relation to the nozzle 16. This movement of the anvil 18 is also necessary to effect the stretching of the upper held by the jaw 106 against the nozzle 16. It will be understood that although the construction herein shown provides convenient means for operating the anvil 18 and the jaw 106 it is not necessary that they be operated in the particular manner shown Smce either may be connected to the power operated mechanism independently of the other, or both maybe connected with the power operated mechanism to operate in the necessary time relation to each other.

The mode of operation of the various arts hereinabove described has been set orth to some extent in connection with the detailed description of these parts, but in order that the mode of operation of the machine as a whole may be more clearly understood, a brief recapitulation of the manner of working ofthe dilferent mechanisms and of their interrelation will be made.

The parts being in the position shown in Fig. l of the drawings, a shoe to be lasted, which has already been assembled on a last, is so presented to the machine that the sole of the shoe will rest upon the inclined surface20 of the anvil 18 with the upper outturned over the projectin margin of the sole and with the side of the last where the lasting to begin substantially in line with the front face of the nozzle 16. If the shoe is: of asize and kind which does not require sj 'ich stretching as would be effected by the use of the aw 106 this jaw is disconnected the treadle 82, If, however, it is detsfr ed to use the jaw 106 the outturned porztibn of the upper is placed between the jaw L06 and the rear face of the nozzle 16 and I e'treadle 82 is then depressed, causing the jaw 106 to clamp the upper against the nozzle 16 and causing the anvil 18 to move the sole and last into opera'tive relation to said nozzle. As the anvil 18 is moved up toward the nozzle 16 it will be noted that the nozzle 16 will engage the upper in the angle formed between the side of the upper and its outturned flange and will not only wipe the upper downward over the side of the last but will force this angle into the angle between the last and the projecting sole margin, or, what is the same thing, into the angle between the shoulder of a shouldered sole and the marginal portion of, said sole. The flange of the upper being held by the jaw 16, considerable stretching or pulling will take place about the end of the nozzle 16 as the nozzle forces the angle of the up or into the said angle between the last an the sole margin. The operator then starts the machine by moving his knee or 5 the side of his leg against the knee lever 142 upon a rock-shaft 144 having a horizontal arm 146 connected to the rod 148 which carries at its upper end a clutch operating wedge 150. The arm 146 surrounds the rod 148 and operates to'move the rod by en agement with one or the other of two ad ustable collars 152, 154, attached to said rod. As the machine is started and before the staple is driven, the horn 30 will be raised through its connection with the cam groove-in the cam disk 98 and will cause the v45 or less;

anvil to clamp the work a ainst the nozzle 16 for the reception of t e staple. it

As already ointed out in the detailed description of t ese parts, the movement of the anvil 18 to bring the last and sole into cooperative relation to the nozzle 16 will cause some tipping of the anvil against the tension of the spring 54 by reason of the fact that the nozzle engages the anvil-in front of the pivot 24; When the horn is ,raised to effect the final clamping of the work and the final adjustment of the anvil 1 8 and the nozzle 16, if the stop has been set to se-' cure a further tipping of the anvil before the horn reaches the upper limit of its movement, the stop 60 will engage the cooperating stop formed upon the adjusting member 58 and will push the rod 40 u to cause the anvil to tip toward a vertica position, thus permittin up er of the so e further about the last and un er any overhanging portions of the side of the last. This tipping of the anvil also serves to bring the staple more nearly normal to the direction of pull of the stretched upper and to cause the legs of the staple to be driven into the sole under the last and out of the way of succeeding fastenings which are to be used in attaching the sole.

Although the machine as herein shown and described is adapted to exert automati rally a clamping and lasting pressure upon the work just before the staple is driven; it has been found in practice that on light work very satisfactory results may be obtained by adjusting the machine so that the only lasting and work clamping pressure exerted upon the work shall be that produced by the manually operated means for moving the anvil-'18 and nozzle 16 into cooperative relation toeach other. Not only has it been found that satisfactory lasting results may be obtained by the manual operation of these parts, but it has also been. found that the pressure exerted in effecting the lasting operation is sufficient to support the work for the staple driving operation.

To secure the most satisfactory operation of the machine it has been found that the adjustment of the anvil 18 should be such that with the length of staple used there is no opportunity for the staple to roject through the bottom of the sole when asting the upper directly to the outsole and that the inclination of the anvil should also be such that the staple will be driven into the sole substantially transverse to the direction of pull of the stretched upper. Although the angle of inclination of the anvil will vary with the nature of the work, the length of the staple, the thickness of the sole, etc. it is usually such that, the staple will be in clined to the face of the-sole at an angle of Such an inclination of the the nozzle 16 to wipe the.

staple, besides increasing the holdin power of the staple serves to bring the legs of the staple un er the bottom 0 the last and therefore out of the way of the needle of the sewing machine which is used in securing the welt, upper and sole together after the shoe has been lasted. Moreover, it has been found that staples inclined as herein shown anddescribed do not tend to work out of the sole by the flexing of the sole as do staples which are driven more nearly normal to the face of the sole.

It will be noted that the process of making stitch-down shoes, in the practice of which this machine is particularly useful, is in itself novel and that the shoe produced by this process is also novel. The novel rocess and the novel shoe are made the subect-matter of separate co-pending applications, Serial No. 725,476, filed October 12, 1912, and Serial No. 863,128, filed September 23, 1914','respectively.'
